It will be hard to find a VR Corrado that hasn't had the motor fucked with somehow, and since you are looking for a stock motor, that will make it even harder. If you aren't prepared to work on a motor then you might as well forget about the Grenade-60 :laugh:

I'd go with the next best thing, a MkIII VR GTI. You might be able to find one of those in a pretty untouched shape.

If you decide to do a turbo ABA... put a 16v head on there. That should net a substantial chunk of power over just a regualr ABA turbo.
